Patent DE-3734902-C1 (DE)
IPC: A61G1/06
Filed: 1987-10-15
Granted: 1989-04-13
Abstract: The known carriages have set-down rollers arranged securely at the front end of a frame. With the carriage lying on the stretcher bearing support, these set-down rollers project further into the inside of the ambulance than do the running rollers of the stretcher itself. The use of the known carriages therefore requires that constructional changes be made to the stretcher bearing supports. 
<??>In contrast, the carriage according to the invention can also be used in the conventional stretcher bearing supports, without changes having to be made to the supports. 
<??>According to the invention, the set-down rollers (68) are arranged longitudinally displaceably on the frame (10), and at the front end of the frame (10) they can be fixed in their position relative to the frame (10) by means of a locking arrangement. By releasing the locking arrangement when pushing the carriage into the ambulance, the set-down rollers (68) push back relative to the frame, i.e. in the direction of the front legs (24), until they are finally situated directly under the front running rollers (78) of the stretcher (72).

Title: Method of reinforcing gas turbine rotor - has balls forced against base surface of slot in rotor to compress it
IPC: B24B39/00
Filed: 1990-05-11
Granted: 1991-08-22
Abstract: The strength of highly stressed areas such as fir tree slots in turbine rotors can be increased by compression rolling the slot surfaces.  This can be done by forcing balls (9) against the base surface of the slot in the rotor (2).  The balls are retained in a linear recirculating track (12,17) machined in a mandrel (7). The mandrel has a tapered section (15) so that, as it is pushed through the slot, the work surface is compressed a prescribed amount by the balls, which have a Rockwell hardness of 60 and may be 0.5 mm to 10 mm in diameter, depending on the form of the slot.  The mandrel will usually have several tracks of balls to cover the slot surface in one pass. ADVANTAGE - Increased service life of stressed component.

Granted: 1997-09-27
Abstract: FIELD: vibration motors, microwelding sets, grinding acoustic devices, as well as various production process based on use of longitudinal-and-torsional vibrations. SUBSTANCE: the method consists in excitation in a waveguide of vibrations of various types, division of the front of vibrations excited in the waveguide into parts, direction of the latters at an angle to its surface on the path equal to Li.k - lambda i/4, where Li - path length of i-type vibrations, k-any integer, lambda i - wavelength of i-type vibrations, their direction is opposite on the same paths, strengthening and conversion of torsional vibrations in the waveguide to vibratory displacements. The vibration motor realizing the method uses a rotor and a concentrator of longitudinal-torsional vibrations, whose narrow part is made hollow and pressed to the rotor. A vibrator is attached to the end of the concentrator wider part. Lugs are made on the lateral surface of the concentrator wider part at an angle to it. The lug ends are stepped. The first steps are made on the lag lateral faces, their planes are perpendicular to the lug axis, the second steps are made on the lug upper and lower faces. The distance between the concentrator lateral surface and the first and second steps equals a quarter of the flexural and transverse wavelengths. The total length of the lugs equals a quarter of the wavelength of longitudinal vibrations. The lugs converge towards the concentrator. EFFECT: facilitated procedure. 4 cl, 5 dwg
